Specification of Letters Patent.

Patented April 13, 1909.

l'o all whom it may concern:

rise and fall in unison. In order to turn Be it known that we, WILLIAM A. ALLEN i said shafts in unison to raise or lower the ele and Bonner B. REED, citizens of the United States, residing at Grants Pass, in the county of Josephine and State of Gregon, have invented new and useful Improvemen ts in Baggage-Trucks, of which the following is a specification. i a The object of the present invention is to rovide a truck which will greatly reduce the abor of transferring baggage or heavy articles in general toa car platform or other elevated surface.

In the accompanying drawing, Figure 1 is a side elevation of the truck; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; Fig. '3 is an enlarged vertical section through one of the slides; Fig. dis an enlarged broken side elevation of a detail of the truck.

- Referring to the drawing, 1 indicates the frame of a truck mounted upon front wheels 2 and rear wheels 3. Said frame comprises, at the four corners, vertical grooved slide- Ways 4 supported by upper and lower oblique braces 5 and 6.

7 indicates an elevator frame having an elevator platform 8, and at the four corners the vertical slides 9, having-tongues-lO which move vertically in the grooves of the slideways 4. Each vertical slide is guided in its lower portion between a pair of 1011 itudinal side beams 22. In recesses in said s ideways are rotatably mounted rollers 12 which abut against the edges of the tongues of said slides, and permit said slides to freely move vertically without friction or binding. On

the inner sides of said slides are secured ver-- mounted at its outer end in hearingsZO secured to blocks 21 secured upon the under sides of a pair of longitudinal side beams 22. At its other end the shaft is mounted on hearings secured on blocks similarly mounted on the under sides of a pair of central longitu dinal 'loearns23. Upon said shafts 19, he-- tween said'beams 23, are secured gear wheel's 2e meshingwitheach other. Thereby shafts turn in unison hutni opposite drrec tions. The directions of motion of the two; shafts, however, are such that the fourshdesf 9, at the corners of theelevator platform,

vator, each short shaft '19 nreiects through the outer side beam 22 and is square at its end, so that it can he turned by a crank handle. To increase the power, in the case of heavy loads, means are provided comprising a gear wheel 25 on each short shaft'lQ meshing with a pinion 26 on a secondary shaft 27, which is likewise extended through the outer side beam. 22 and is squared at its end so that it can be engaged by a crank handle.

In order to retain the elevator at any height, to which it hasbeen raised, there is secured upon each shaft 19 airatchet wheel 28, which can be engaged by a pivoted dog 29. Above said dog is a slide piece 39 having secured thereto stems 31 -which pass through a slot '32 in the outer side heaniand have secured on their outer ends he'ads To the-under side of this slide piece'is secured abow spring '34. In the position shown in Fig. 4, said s ring resses n on the rear end of tne dog an tents to lii'tt 1e nose of the dog out of contact with the-;ratchet wheel, so that the elevator frame is free descend. But, when said slide is moved to the left, said spring thenpresses uponthe forward part of the dog and forces its nose into contact with the ratchet wheel, so that then, while the shafts 19 can be turned to raise the elevator they cannot be turned backward.

The mode .of operation of the apparatus will readily be understood from the foregoing description. The baggage, orother heavy articles, having been loaded on to the elevator platform, the truck is wheeled to the place desired, and the elevator is then raised by turning either a single crank handle applied. either to one side or two crank handles ap lied to opposite sides of the truck. if t e load is heavy, the crank handles will be appliedto the shafts 2'7. The elevator platform can thus be raised to the proper level to await the arrival of a train, whereupon the baggage can readily be transferred from the nlatiorm to the baggage car: in case heavy aggage is piled'u on the truck, the elevator can he raised,after the topmost baggage has been transferred, in

' order to bring the lower baggage up to the level of the baggage car.

1 we cia' ne I,

1. in apparatus the character are scrihed, the *oomlnnatron oi rectangul r wheeled truck having guideways at'its four corners, an elevator having slides guided vertically by said guideways, racks on said slides, gear wheels engaging said racks, two

parallel} gear shafts upon which said gear wheels, are mounted inpairs, two parallel operating shafts, extending res actively" through'opposite sides of the true frame, and provided with means for turning the wheels meshing with said racks, an operating shaft constructed to be moved by a suitable handle, a ratchet wheel on said shaft, a

sprin -actuated' do for engaging said ratchet wheel to prevent t e rear movement of the shaft, means for moving the s ring to engage the dog either to depress t e same to engage the ratchet wheel or to move it therefrom, and an operative connection between said shafts and gear wheels, substantially as described. e

3., In an. apparatusof the character de scribed, the combination of a truck frame having 'guideWaya'wheels therefor, an elevator frame having vertical slides movable in said guideways, racks on said slides, gear wheels meshing with said racks, an operating shaft constructed to be moved by a suitl :set our hands in the erases ablehandle, a ratchet wheel ousaid shaft, a

springectuated dog for engaging said ratchet wheel to prevent the rear movement of the shaft, a slidable device upon which said s ring is'mounted, and means for sliding said eviee, said spring in one position ressing said dog against said ratchet whee and in another positionraising it therefrom, andan operative connection between said shafts and gear wheels, substantially as described. 7 4. In an apparatus of the character described, the comb inatiorrof a truckfframe having guideways,wheels therefor, an elevator having slides vertically movable on said guideways, the truck frame having at each side a pair of between which cally, racks on said slides, transverse shafts, gear wheels on said shafts engaging said racks, sprocket wheels on said shafts, transverse operating shafts extendin inward from opposite sides of the true; frame,

sprocket wheels von said operating shafts,

sprocket chains connecting said sprocket wheels withthe first named sprocket wheels and gear wheels on said operating shafts meshing with each other, whereby they turn in unison, substantially as described.- In testimony whereof we, have hereunto presence of two subscribing witnesses'.
